This is a new LabTech UV-VIS Spectrophotometer BlueStar B.

BlueStar UV-Vis spectrophotometers with fixed bandwidth of 1 nm or 2nm offer high-performance, reliability and exceptional value.

Features

Large LCD and friendly interface for ease of operation.
Optimized optics improve signal to noise ratio.
Micro-stepping drive simplifies the mechanical complexity, reduces maintenance and improves the instrument longevity.
Advanced 32bit CPU guarantees sophisticated data processing and graphic display.

Automatic Six-position Cell Holder

Spacious sample compartment can hold up to a 100mm cell
Various types of cell holders can be selected for different applications
Auto- rotary six-position cell holder, shortens the sample exchange time
Entrance port and exit ports of the light beam in the sample chamber are protected by quartz window, to prevent the optical system from contamination.

High-Quality Components

Top quality key components from well-known manufacturers include deuterium lamp, silicon photodiode detector, and holographic grating.
